Just recently got the Slim, where I have the system it's quite dusty. I was just curious how much of a problem dust can cause since I lay my console flat instead of upright, since it's 1000% quieter when a disk is spinning inside and I don't have to worry about the disks getting scratched up or anything, and on the Slims the top of it, where the dust lands, has the vents, whereas the old consoles had the vents on the side and back. I do install the games to the hard drive so they don't spin while I'm playing them, but when I want to watch a DVD, there's nothing I can do about that. So I was just curious if there was something I can do, or something I should do. I noticed that one of those after market cooling fans would help with the problem since it covers the vent from being exposed directly on top, BUT I've also hears a lot of mixed reviews about them, the fact that they do cover a lot of the vent has a lot of people saying they do as much harm as they do good. Any help is appreciated, thanks in advance.
